BRICK-MACHINE.

SPECIFICATION forming part of Letters latent No. 283,184,-date d August 14, 18 83.

Application filed -May 14; de (no model.)

Be it known that we, WILLIAM WOODWARD and ABEL B. WOODWARD, citizens of the .United States, residing at Nashville, in the county of Davidson and State of Tennessee,

have invented a new and useful Brick-Machine,

of which the following is a specification, reference being had to the accompanying drawings.

ed out in the claims- In the drawings hereto annexed Figure 1 is a side view of our improved brick-machine.

Fig.2 is a top view of the same. Fig. 3 is a longitudinal vertical sectional view taken centrally through the machine. Fig. 4. is a 1ongitudinal vertical sectional view taken through the plungers and operating mechanism. Fig.

e, .5 is a vertical transverse sectional view on the lineal x in Fig. 1, and Fig. 6 is a detail view of the main cam-wheel.

The same letters refer to the same parts iii all the figures. A g

A in the drawings designates the frame of L our improved brick-machine, which consists, essentially, of the base B, top 0, and uprights E is a horizontal or end pieces, D D, connecting the said base and top. e i A partition arranged in the frame not far from the top and extending at Y one end, so as to form a bracket, F. This partition or floor serves to support'a slide, G,

arranged to move longitudinally, and having one or more inclined slots, H, (according to the desired capacity of the machine,) the upper and lower ends of which have horizontal extensions I. h

The top plate, 0, of the machine is provided with hoppers J, arrangedin pairs, as shown.

I In the drawings heretoannexed, which represent. a machine with capacity for pressing four a bricks at a time, four such hoppers are shown.

The hoppers are arranged in front of the ver- 0, corresponding in size and location to the boxes K, extenddownwardly, as shown. The boxes 0 contain vertically-movable plungers or followers P, the lower ends of which are provided with downwardly-extending verti- 'cally-slotted' straps Q. The 'plungers P are connected in pairs by means of transverse rods B, for the accommodation of which the inner ends of the boxes are slotted vertically, as at S. The inner ends of the upper boxes, K, are likewise slotted vertically at 'T to admit of the vertical movement of the connecting-rods of the plungers and their friction-rollers. The hoppers J extend through the top plate, 0, of the machine, and their discharge-openings are 011 a level with the lower ends of the boxes K. The slide G is provided on both sides with laterally-projecti'ng boxes U, one foreach hopj per, which serve to carry the dirt or clay from the hoppers to the mold-boxes O. The boxes U are provided with laterally or forwardly extending top flanges,V, which, while the said boxes carry the clay to the mold-boxes,

serve to cut off the clay from the hoppers.

Bearings are formed in the ends of the frame below the floor E for a longitudinally-movable slide, W, which is forced automatically in a with the slide W, and their upper or horizontal arms are provided with slots Z, working upon or over the rods R, that connect thelower plungers, P. It will be seen from this construction that by reciprocating the slide WV the plungers P will be raised or lowered; also, that the extent to which they may be lowered will depend upon the extent to which the spring X may force the said slide W in a forward direction. This may be regulated by means of a pin, A adjustable in any one of a series of perforations, B in the front end of the slide WV, and adapted to bear againstthe front end of the frame,

thereby preventing the slide from moving in a rearward direction beyond a certain point.

' be lowered in the said boxes.

2 ears-r G O are segmental cams pivoted to the base B of the frame below the mold-boxes O, and connected in pairs by rods D as shown. Similar cams, E, are arranged above the cams 0", bearing against the rims of the latter and con nected in pairs by transverse rods F The cams E are provided at their upper ends with transverse laterally-proj ecting pins G working in the slots of the straps Q, that extend downwardly from the plungers P, with which the said cams are thus connected.

H is a slide moving longitudinally in suit able bearings in the ends of the frame between the cams O and E, and provided with loops 1 that encircle the connecting-rods D and F of said cams. It will be seen'that by the operation of the slide the cams are operated so as to force the plungers upwardly intermittingly by pressing against the under sides of said plungers.

J is a vertical shaft journaled in suitable hearings in the bracket F, and in a corresponding bracket, K extending from the end of the machine. This. shaft, to which motion may be communicated in any suitable manner and from any power desired, serves to drive the machine through intermediate mechanism, which we shall now proceed more fully to describe. The

upper end of the shaft J has a cam-wheel, L

consisting of a circular disk, M", provided with two pairs of wings or cams, N N h 2 M, the wings of each pair extending, respectively, from the upper and the under side or face of the disk, and on diametrically-opposite sides of the same, one being slightly in advance of the other.

The slide G is provided with a stem, 0 having friction-rollers I and Q of which the roller 1, at the outer end of the stem, is adapted to engage the wings or cams M and N while the inner friction-roller, Q", is adapted to en gage the wings or cams l and N. The inner end of the stem 0 has a slot, R to admit of the passage of the wings M and N when the cam-wheel revolves. slide G will be reciprocated twice during each revolution of .the sh aft. Owing to the disposition of the wings or cams, as described, the slide is first carried in a rearward direction, thus causing the boxes attached to said slide to carry the proper quantity of clay from the hoppers to the mold-boxes, into which the clay drops automatically from the bottomless carrying-boxes. The size of the mold-boxes may be regulated in the manner described by regulating the extent to which the plungers may The slide having been carried rearward, so as to fill the mold-boxes, (by which same movement of the slide the plungers L are raised, so as to permit the clay-carrying boxes to pass under the said plungers,) is instantly returned in a forward direction to its original position, thereby lowering the plungers L so as to press the clay in the mold-boxes into shape without, however,

exercising the heavy pressure required to mold By this mechanism the and compress'the brick. In this position the slide and plungers L remain temporarily until the slide is acted upon by the next set of 'wings or cams. In the meantime other mechanism is thrown into play as follows: The lower end of the shaft J 2 has a crank, S which works in a transverse slot, T in a plate U at the end of the lower slide, H by which the cams G and E are operated. This crank extends from the shaft between the sets of wings of the cam-wheel above referred to. By this mechanism the cams will be operated in such a manner as to force the plungers P in an upward direction by pressure against the under sides of said plungers, while the upper plungers, L, are lowered, thereby compressing the bricks in the mold-boxes. The bricks having thus been compressed to the desired extent, the next step will be to eject them from the mold-boxes. This is accomplished by the slide WV,which is provided at its outer end with a friction-roller, V acted upon by the wings W of a cam-wheel, X secured upon the shaft J at the level of the said slide. The wings of the said cam-wheel are so disposed that when the upper plungers, L, actuated by the slide G, begin their upward course, they shall, by a short quick movement, force the said slide forward against the tension of the spring, thus quickly raising the plungers I and the bricks supported upon the same to the level of the floor E. In this position the plungers P are retained only for a moment, or long enough to cause the clay-carrying boxes U to push the said bricks off the plungers and onto the floor E, from whence they are to be removed either by hand or by any suitable mechanism. This having been accomplished the wing W releases its pressure upon the slide, and the latter will then be instantly forced back to its former position by the spring X, thus permittingthe plungers P to drop and the boxes U to empty themselves into the mold-boxes. The operation is then repeated. 7

The sides of the boxes'O have openings Y, and the plungers l? are provided with 0penings Z extending from their faces to their sides, so asto communicate with the said openings Y This is for the purpose of permitting the air contained in the mold-boxes to escape, instead of being compressed by the plungers, and thus interfering with the operation of the machine. c

lVe claim and desire to secure by Letters Patent of the United States 1. In a brick-machine, the combination of the frame, the vertical guide-boxes arranged in pairs and having slotted inner sides, the vertically-movable plungers connected in pairs bytransverse rods having friction-rollers, and
